.SPECIFICATION forming part of Letters Patent No. 629,786, dated August 1, 1899.

Application led May 8, 1899. Serial No. 716,012. (No model.)

To @ZZ whom, t may'concern/:-

Be it known that I, JOHN H. Goss, a citizen of the United States, residing at Waterbury, in the county of New Ijlaven and State of Connecticut, have invented a certain new and useful Improvement in Inflation and other Valves, of which the following is afull, clear, and exact description.

This invention relates more especially to xo that class of valves which are used for inflating the pneumatic tires of bicycles; and the invention is particularly designed for use in connection with those valves which comprise a shell or casing to be applied to a rubber cot and containing a spring-pressed plunger, which normally closes the valve against the escape of the air from Within the tire and which valve is held in place bya hollow screwplug inserted in the inner end of the shell or zo casing. The shell or casing is provided with a removable cap and is also provided with an internal screw-thread, to Which may be applied the iniiating apparatus when the cap is removed.

The invention consists of a hollow screwplug` formed of sheet metal; and the invention also consists in the combination of such a hollow screw-plug With a valve of the character described or of other suitable construction, all as I will proceed now more particularly to set forth and linally claim.

In the accompanying drawings,illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is an elevation of an inflation-valve of substantially the construction illustrated in the patent granted to the Scovill Manufacturing Company as my assignees on 'September 20, 1898, No. 610,985. Fig. 2 is a longitudinal 40 section thereof, these Atwo views showing the hollow plug of this invention applied. Fig. 3 is an elevation of the hollow plug detached and containing a knurled head. Fig. 4 is an elevation of the plug detached and showing it Without the kuur-ling of the head. Fig. 5

is a vertical section which illustrates the two plugs of Figs. 3 and et.

The shell or casing @may be provided With grooves 1J to assist in applyingthe valve to the rubber cot of the tire, and it is also pro 5o vided with a valve-seat o, an external screwp thread d to'receive the cap e, of anysuitable construction, and the internal screw-threaded chamber f to receive the inflation-pump connection. g is a valve or plunger constructed, preferably, in accordance with the patent hereinbefore referred to and seating against the seat cand normally held thus seated by the spring h. The inner end of the shell or lcasing is provided with a screw- 6o thread t' to receive the plug la, which plug serves to hold the spring in place, and. consequently the valve or plunger. This plug 7c is made hollow for the passage of the air from the pump into the tire. Heretofore such plugs usually have been made of solid wire or rod bored or otherwise treated to adapt them for use in connection with inflationvalves of this general character. I have found that these plugs may be made very 7o much more economically by producing them from sheet metal properly manipulated to provide a rounded or globular head la', which,

as shown in Fig. 3, maybe knurled, or, as shown in Fig. Il', may be left plain or not 75 knurled, and a shank portion k2, Which is externally screw-threaded to adapt it to coperate with the screw-thread i within the shell or casing of the valve. The inner end of this shank is curved inwardly, as at k3, and 8o perforated at 1704. By curving in the inner end of the plug it is more easily guided into cooperation with the screwthread of the shell, and by making the head curved or of approximately globular form the valve as a whole is more easily entered into the cot or other device by which the said valve is counected with the tire or other object to be inflated.

The plug is screw-threaded into the shell 9o or casing in order 'to' be readily removable for obtaining access to the valve mechanism contained within said shell or casing.

I do not limit my invention to a plug produced solely from sheet metal, although a hollow sheetonetal plug is the preferred construction and constitutes one portion of this invention. It is within my invention to make of any suitable blank a plug` having a substantially or approximately globular head with or Without knul-ling.

What I claim isl. An ination-valve, comprising essentially a shell or casing, an internal valve mechanism, a cap at one end and a removable plug at the other end, the said plug having an approximately globular end orhead, a screw-threaded shank and an inwardlycurved and perforated end, substantially as described.

2. A valve for inflation, of any approved construction, having a plug screw-threaded in to one end thereof and provided with an approximately globular head, the said plug being formed of sheet metal, substantially as set forth.

3. AA plug for inflation and other valves, constructed of sheet metal and having a screwthreaded shank and an approximately globular head, substantially as described.

4. A plug for inflation and other valves,

JOHN H. GOSS.
